Question

A Hydraulic Press has a RAM of 300 mm diameter, and plunger 45 mm

diameter. Find the weight lifted by the hydraulic press, when force

applied at the plunger is 50N.
​

Answer 1

Answer:

Weight on the ram F=mg=1000×10=10000

Using Pascal's law

A

F

=constant where A=πD

F

p

⟹F

p

=100 N =10 kgf

Thus, force required on plunger is 10 kgf
